Description
There is a known issue (bug id 263864) in which 1Gig NP4 ports will remain down after reboot. The problem happens randomly and only when auto-negotiation is used.
Workaround: Fix speed & duplex to 1000full as outlined below.
Scope
Unit with NP4 1Gig ports -- e.g., FGT3240C 1Gig port from port13 to port28
Workaround
Long-term workaround:
To avoid the problem with auto-negotation, configure the speed as follows:
From FGT 3240C CLI :
config system interface
edit "port28"
set vdom "root"
set type physical
set snmp-index 29
set speed 1000full
next
end
In this way, you will avoid encountering the problem.
Temporary workaround:
If you encounter the problem, you can change the administrative status in order to restore operation of the interface which is down:
config system interface
edit port27
set status down
end
wait for one minutes
edit port27
set status up
end
Sometimes, the admin status change (up to down and then down to up) must be repeated
==> If the speed interface is configured (forced to a fixed value) , this situation will not be faced.
